"5 684,549, filed August, 10. 1933 now abandoned and Serial No. 696,037,filed October 1, 1933, Patent No. 2,015,632, dated September 24, 1935.

Themain feature of the invention relates to latex garments, such as babypants-which are relatively inexpensive to manufacture, which aredurablein construction'and which are easy to apply to the wearer.

A further feature of the invention relates to novel forms on which suchgarments can be made.

These and other features of the invention will appear from the detaileddescription and claims when taken with the drawings in which Fig. '1 isa front view of one style of garment made ac- 2 cording to the presentinvention; Fig. '2 is a side elevation of the same; Fig. 3 shows aslightly modified style of garment and Fig. 4 is a side elevationthereof; Fig. 5 is a vertical section taken substantially on the line5-5 of Fig. 3; Fig. 6

is a fragmentary sectional view taken through the fastening openings inthe garment and indicating the type of fastener that may be usedtherewith; Figs. 7 and 8 respectively show a front elevation and a sideelevation of a preferred type of form for making the garment shown inFigs. 1 and 2; Fig. 9 is a front elevation of still a different type ofform which is suitable for making simultaneously two garments of thekind illustrated in Fig. 3; and Fig. 10 is a side eleva- -tion of thisform; Fig. 11 is a section through this form taken substantially on theline llll of Fig. 9; Fig. 12 is a fragmentary sectional view thereoftaken substantially on the line l2l2 of Fig. 9; Fig. 13 illustrates afiat type of form on which two garments can be made simultaneously; Fig.14 is a vertical section of the same taken substantially on the line I4-H of Fig. 13; and Fig. 15 is a fragmentary section through anyof theforms of Figs. 9 to 14 inclusive, illustrating 45. a lateral margin ofthe form together with bosses ,55 gin of this opening'is provided with areinforced pairs of openings I3, the edges of which openings edge Iwhich is semipear-shaped incross section (see Fig. 5). The pants arealso provided with, leg openings 8 and 9, the margiri'of each Tegopeningbeing reinforced by an accumulation of the material thereat which'accumulatioiiQter- I minates in a feather or torn edge. At 'each "side"of the pants the material has a slit I2 therein which extends from theleg opening tothe opening in the top of the pants. The latex at eachmargin ofeach slit is of increased thickness to 10 provide areinforcement which terminates in' a feather edge as indicated at I1, I!in Fig. 6. At

each side of the slit there are provided spaced are reinforced as shownat H! in Fig. 6. These 5 openings are adapted to receive fasteningmeans, such as buttons l4, although any'suitable type of fastener otherthan buttons can be usedwithout departing from the spirit of theinvention.

It will be noted that the leg openings 8 and 9 as shown in Fig. 1 facetoward the front ofthe pants" so that they tend to conform to the bodyof the infant while worn. I

The modified style of the pants l5, shown in Figs. 3, 4 and 5, differsfromthose illustrated in Figs. 1 and "2 in that the front andback of thepants areof identical shape, since no attempt has beenmade to shape themto the body of the infant. Also the leg openings are of' different shapein that no attempt has been made to make 30 the pants tightly engage thelegs of'the infant during use. However, this style .of pants lendsitself to being manufactured on a simpler type of form. The top edge ofthese pants is also reinforced by a margin l6 which is semipear-z shapedin cross section. while the other free edges of these pants arereinforced by accumulations or ridges of the material which terminate infeather or torn edges such as indicated at H (Fig.1 6). Likewise, thematerial at the margins of the 40 button openings I8 is reinforced by anaccumulation or ridge terminating in a feather'or torn: edge I9 similarto that shown at IT. However, the edge I!) may be formed by cutting,clicking or stamping out the portion of the layer within thereinforcement. It will be understood that these pants are fastened onthe infant by means of buttons such as I4 (Fig. 6) inserted intheIregistering pairs of openings l8.

The pants shown in Figs. 1 and 2 are made by dipping a form 20 (Figs. 7and 8) one or more times into a bath of liquid latex, such as an 7aqueous dispersion of rubber, with a suitable drying interval betweeneach'of the dippings; The form 20, which has a generally rounded out-- 5to thatv shown; at 29 of Fig. 15. These bosses line is provided at itslower edge with a pair of fins 2| adapted to be received in the femaleportion of a rack (not shown) so that a plurality of forms may be dippedsimultaneously. The front face of the form as viewed in Fig. '7 isgenerally fiat, whereas, the rear surface 2| indicated by the dottedline in Fig. 8 is dished or concave to provide an increased area of thelayer deposited thereon, so that the pants will be shaped to the body ofthe infant. Theupper edge of the form-as shown in these views isprovided with raised portions or bosses 22 which are generally offlattened elliptical outline, which. rise abruptly from the surface ofthe form, and

which terminate in an abrupt edge: 24-. The-lower margin of the formalso terminates in an abrupt edge 25, being defined by intersectingsurfaces. rupt edge 25 of the form by a fin 26 which projects abruptlyfrom the form and each exposedcorner thereof is. abrupt. or sharp-forpurposes to be defined. A series of circular bosses 28 also projectabruptly from the form and also terminate in an abrupt: or sharp edgesimilar are; arranged inpairs, each pair being separated by a fin 26.

In-making of pants on the formshown in Figs. '7 and 8, the form issubmerged into the mentioned. bath of latex and then slowly removedtherefrom. Then the form with the deposited layer thereon is held withits abrupt edge lowermost and with this edge in a substantiallyhorizontal, position: until the deposited layer is dried. Thereafter,the form is again dipped and the form removedfrom the bath and held withthe abrupt edge 25 substantially horizontally as before mentioned untilthe second layer isdried. These operations: are repeated until a.garment of the desiredthickness isformed. Although it has been mentionedthat layers are thus deposited, the. finished product does not disclosesuch layers but appears to be a. homogeneous mass. When a product of thedesired thickness has thus been deposited, dried and/or cured, the

portions ofv the layer on. the faces of the bosses 22 and the ribs 26are strippedor. torn away leaving the leg openings 8 and 9 and thelateral slits l2 with the margins thereof reinforced by a ridge oraccumulation of latex terminating in a feather or: torn edge. However,the edge of the product deposited adjacent the abrupt edge 25 will bereinforced by an accumulation of the material similar to one-half a teardrop in. cross section, and the excess product present. on the:

fins 2| is stripped awayas far as the abrupt edge 25. The portions ofthe deposited layer on the ends of the bosses 28 are torn away toprovide-the desired openings l3 in the product.

. The remaining operations of treating the product, preparing it formarket are similar to those well-known in the art and need not be hereinset forth.

The garment shown in Figs. 3, 4 and Scan be made on the form 30 of Figs.9, 10 and 11. This form is generally saddle-shaped and is adapted tomaking. two garments thereon simultaneously, since the form is hollow.This form comprises two flat panels 3| and 32 which are joined togetherby the curved. upper portion of-the form.

Each boss 22 is connected" to-the ab-- sectional shape is not essentialas long as the border rises abruptly from the junction (Fig. 11) of theform. As illustrated the borders 33 and 34 have abrupt edges 36. Aseries of circular bosses such as 31 project from both faces of the formadjacent each border to define buttonholes in the resulting garment.Supports 38 project from the sides of the borders of the form and serveto suspend it during the dipping operations.

Inmaking a garment on thiszform, the form is dipped one or more times,with a drying interval intervening in the latter case, into a bath ofliquid' latex, until a layer of the desired thickness is accumulated,dried and/or cured on the surfaces of the form. The excess portions ofthe layer onthe surfaces of the borders 33 and 34 are torn. or strippedaway as far as the abrupt edge 36 and also from the faces of the lugs31, leaving an accumulation of reinforcement of the layer in. thejunction. of these parts with the main body of the. form. At the abruptedges, of these parts, however, the garment will have a torn or featheredge. However, onthe extreme lower-=edges of the form, the layer willaccumulate a reinforcement whichis substantially semipear-shaped incross section as indicated at 45- in Fig. 14. It will be understood thattwo similar garments are made simultaneously on theform, the garmentvmade on the inside of the form being somewhat smaller.

A garment similar to that shown in Figs. 3, 4- and 5 except that it isin no Way. shaped to the body of the wearer, can bemade on the flat form40 illustrated in Figs. 13 and 14. Form 40 is also adapted to make twogarments simultaneously, one garment being made on each face of theform. This form, differs from that shown in'Figs. 9, 10 and 11 in thatit is a flat plate with all of its edges except the lower edge-4|.bounded by a border 42 which is identical in character with theborders33'and 34 in the last described form. The formalsohas circular bosses 43projecting from the-face. thereof, to define buttonholes in theresultinggarment.

A pair. ofv garments can be made on this form in accordance with theprocesses already described. It will be understood, however, that theuppermost edge 44 of the deposited garments will have a cross sectionsimilar to that shown in Fig. 14 and will terminate in a torn or featheredge. The lower portions of the garments deposited on this form,however, have reinforcements substantially identical with the shapeindicated. at 45 in Fig. 14.

While several embodiments of the invention have been disclosed, it willbe understood that this invention is capable of still furthermodifications and that this disclosure is intended to cover anyvariations, uses, or adaptations of the invention falling within thescope of the appended claims.-

What I claim is:

1. A form for making latex pants or the like by dipping, comprising apanel having a constricted intermediate portion, said panel beingbounded at substantially its entire margin by an abrupt edge.

2. A form for making latex pants or the like by dipping, comprising aplate having a panel on each surface thereof, each panel having aconstricted portion and being bounded by an abrupt edge.

3. A form for making latex pants or the like by dipping, comprising afiat panel having a con- V 5. A sheet-like form for makingalatexparticle on each of the opposite surfaces thereof simul-; taneouslyby'deposition, said form comprising a plate folded transversely uponitself and having similar article-defining outlines'on eachsurfacethereof, and marginal reinforcement-generating means for each surface ofthe form.
